Juno is a NASA New Frontiers mission to the planet Jupiter.
Juno was launched from Cape Canaveral Air Force Station on August 5, 2011 and will arrive in July 2016.
The spacecraft is to be placed in a polar orbit to study Jupiter's composition, gravity field, magnetic field, and polar magnetosphere. Juno will also search for clues about how it formed, including whether Jupiter has a rocky core, the amount of water present within the deep atmosphere, and how its mass is distributed. It will also study its deep winds, which can reach speeds of 618 kilometers per hour (384 mph).
